Definitions

  • the invention relates to an electric toothbrush with a brush part in which a rotatably mounted shaft is accommodated and on which a rotatably mounted bristle holder is held, the axis of rotation of the bristle holder being arranged at an angle, in particular approximately at right angles to the axis of rotation of the shaft, and means being provided are for alternately driving the bristle carrier through the shaft.
  • a device for cleaning and polishing teeth in which a bolt projecting eccentrically from a shaft engages in an outer annular groove of a displaceable cylinder, which furthermore has a conical central bore into which a tool can be inserted to clean the teeth.
  • Rotation of the shaft causes the cylinder and thus also the cleaning tool to move up and down via the eccentric bolt.
  • the cleaning tool can be rotated about its longitudinal axis due to the outer ring groove, so that the tool adjusts itself with regard to its angular position, for example when it is inserted into a space between teeth.
  • the cleaning tool does not alternate about its longitudinal axis.
  • GB-PS 1208149 describes a cleaning device which has two concentric cleaning rings which are driven in opposite directions to one another by means of bevel gear drives.
  • the object of the invention is to provide an electric toothbrush which, with a simple construction, allows the bristle holder to be driven alternately by a large angle of rotation and whose shaft can also be driven in a rotating or alternating manner, if necessary.
  • This object is essentially achieved in that the shaft is provided with a driver arranged eccentrically to its axis of rotation and the bristle carrier is provided with a sensor arranged eccentrically to its axis of rotation and the driver is coupled to the sensor.
  • a rod is provided as a driver, which is received in a bore arranged approximately parallel to the axis of rotation of the shaft.
  • the driver thus consists of only one component, namely the rod arranged parallel to the axis of rotation, which is expediently made of metal.
  • a pin can be provided as the pickup, which is received in a bore arranged approximately parallel to the axis of rotation of the bristle carrier.
  • the receiver namely the pin arranged parallel to the axis of rotation of the bristle carrier.
  • This pin is also expediently made of metal. It is now possible that the rod and the pin are firmly connected to one another or are made in one piece. It is advantageous to design the receptacle for the rod and the pin such that the rod and the pin can rotate in the respective receptacles and can move in their axial directions.
  • the rod is provided at its free end with an eyelet which is penetrated by the pin.
  • the bore of the rod is advantageously designed such that the rod can rotate and move in the axial direction.
  • the eyelet is rotatable about the pin and movable in its axial direction.
  • the embodiment in which the rod is provided with the eyelet also offers the advantage of simple and quick assembly.
  • the use of the eccentrically arranged rod and the eccentrically arranged pin also has the advantage that the angular range of the alternating rotational movement of the bristle carrier can be adjusted in a simple manner by varying the degree of eccentricity of the rod or pin . It is therefore possible to enlarge or reduce the range of the angle of rotation of the alternating rotary movement of the bristle carrier by selecting the distance, for example, of the rod from the axis of rotation of the shaft.
  • the bristle carrier is pivotally mounted in the brush part.
  • the bristle carrier is provided with an axis which is received in a spherical bearing, for example by means of a bearing ball.
  • the bristle carrier can thus, on the one hand, be rotated about its own axis of rotation as before, but can also be pivoted about the spherical bearing.
  • the driver is designed as a rod and the sensor is designed as a pin
  • the bore of the rod is designed such that the rod can rotate but cannot move in its axial direction the result is that the bristle carrier is set in an alternating rotation and wobble movement.
  • the bristle carrier has an outer and an inner bristle ring, both of which are rotatably mounted about the axis of rotation of the bristle carrier.
  • a sensor is assigned to the outer and the inner bristle ring, each sensor being in turn coupled to a driver.
  • the carriers are expediently arranged eccentrically on opposite sides of the axis of rotation of the shaft. This has the consequence that the outer and the inner bristle ring alternate in opposite directions of rotation, whereby the cleaning effect of the toothbrush is improved.
  • the bristle carrier has an eccentric bore which opens at least to the underside of the bristle carrier, the receiver and driver being designed as a one-piece transmission element. This measure ensures extremely simple assembly of the transmission element in the toothbrush.
  • the bore advantageously has an opening to the side wall of the bristle carrier over a central section of the bristle carrier. The opening allows the rod of the transmission element to exit, which can then be easily inserted into the receptacle provided in the shaft.
  • the transmission element is advantageously T-shaped, the rod preferably having a smaller diameter than the pin. This gives the possibility of mounting the pin on both end sections in the bristle holder despite simple mounting of the transmission element on the bristle holder.
  • the transmission element can also be L-shaped or have other suitable shapes.
  • an especially long-slot-shaped opening which extends radially to the side wall and which preferably has a constriction formed by projections.
  • the narrowing of the elongated slot-shaped opening formed by the lugs serves to also support the section of the pin pointing towards the underside of the bristle holder on the bristle holder. Since the rod preferably has a smaller diameter than the pin, the rod can be passed through the constriction during assembly on the bristle carrier, while after the completion of the assembly process, the approaches form a kind of abutment for the pin. The other section of the pin is stored in the bore in the bristle holder.
  • an essentially sinew-like cut which is open on the underside and which extends away from the bore to a side wall section and is provided with a further incision provided in the side wall is connected.
  • the transmission element is also mounted in such a way that it is inserted into the bore from below with the pin, the transmission element being positioned so that the rod is received in the incision open to the underside.
  • the transmission element is displaced axially with respect to the bristle carrier to its upper side until the rod comes to rest in the incision provided in the side wall. Then the rod about the pin can be pivoted radially outward from this position into the final assembly position.
  • This further embodiment has the great advantage that the pin is fixed to the bristle carrier at both end sections and is also secured against slipping out of the bore.
  • This type of mounting of the transmission element on the bristle carrier is also extremely simple and can be done mechanically.
  • the axis of rotation of the bristle carrier is arranged approximately at right angles to the axis of rotation of the shaft and / or the sensor designed as a pin is arranged approximately parallel to the axis of rotation of the bristle carrier.

Abstract

Une partie (24) de brosse à dents électrique contient un arbre rotatif (34) qui peut être animé d'un mouvement alternatif ou rotatif. L'axe de rotation (54) d'un porte-soies (38) monté rotatif sur la partie (24) de la brosse est à peu près perpendiculaire à l'axe de rotation (52) de l'arbre (34). Une tige (102) à peu près parallèle et excentrique est montée mobile dans l'arbre (34). Une cheville (112) à peu près parallèle et excentrique par rapport à l'axe de rotation (54) est retenue dans un épaulement annulaire (61) du porte-soies (38). La cheville (112) traverse de manière mobile un ÷il (103) située à l'extrémité libre de la tige (102). Lorsque l'arbre (34) est animé d'un mouvement rotatif ou alternatif, ce mouvement est transmis par la tige (102), l'÷il (103) et la cheville (112) au porte-soies (38). Le porte-soies (38) est toujours animé d'un mouvement de rotation alternatif, que l'arbre (34) soit animé d'un mouvement alternatif ou rotatif.
